BLAKE2 is an improved version of BLAKE, one the finalists in the NIST SHA-3 competition. Like BLAKE or SHA-3, BLAKE2 offers the highest security, yet is fast as MD5 on 64-bit platforms and requires at least 33% less RAM than SHA-2 or SHA-3 on low-end systems. This implementation uses the BLAKE2b variant of the algorithm which is optimized for 64-bit systems. The algorithm was designed by Jean-Philippe Aumasson, Samuel Neves, Zooko Wilcox-O'Hearn, and Christian Winnerlein.

blake2 package is uploaded to pypi. you can use

• easy_install blake2
• pip install blake2

1. git clone https://github.com/darjeeling/python-blake2.git
2. cd python-blake2
3. python setup.py install

you shoud apply same key to get same hash. initialzed key shoud be given.

import blake2
blake2.blake2( data [, hashSize = 64,   key = "",  rawOutput = False ] )
blake2.blake2b( data [, hashSize = 64,   key = "",  rawOutput = False ] )
blake2.blake2s( data [, hashSize = 32,   key = "",  rawOutput = False ] )
